Try a 4.7K resistor, or so, to Gnd (instead of the LED circuits).
I appreciate the pic, but if this doesn't work out - could you take another after tidying things up some, and we can see all of the connections (ground wires, + wires, all of it), leaving the observer to assume nothing, and just as they are under test?
